I wouldn’t dream of telling Elon Musk, who recently became Twitter’s largest shareholder, how to make a profit. But I do know something about free speech. If Mr. Musk really wants to make the social media giant a force for free speech, here are 10 things he can do:
1. Leave more content in place. Twitter has rules on posts, and most of the enforcement is done by artificial intelligence. The algorithms err on the side of removing material that might violate Twitter’s rules. Instead, they should err on the side of leaving questionable material until there has been human review.
